A kind of method that in the commercial affairs group, realizes DNH group of the present invention, the step that the cross-module selection subscribers feeder of group in the commercial affairs group of Centrex system is adopted, begin the idiographic flow signal from the Calling Side module of calling out and see also Fig. 1, specifically may further comprise the steps:
(4) after call number is received in call proceeding this number is carried out number analysis, when discovery was ordinary call, then the resume module at called number place was issued calling in this call proceeding;
(5) after the module at called number place is received this message, determine whether called number is number in the group, if not, then by the ordinary call flow processing, if number in the group then judges whether it is number CENTREX group in, number is then pressed other group flow processing in the group;
(6) if this called number is a number in the group, then find the group attribute at its place, and judge whether it is DNH group, or other groups, be line selection or polling; Enter two each and every one different handling processes respectively according to this group attribute type difference.If DNH group then enters the DNH call flow; If MLH group then enters the MLH call flow, the MLH call flow does not belong to the scope of the invention, can not exert an influence to the present invention, does not give unnecessary details herein.
The DNH call flow diagram of the inventive method as shown in Figure 2, its concrete steps also comprise:
A, in the CPU (central processing unit) MP of the module at each called number place, be provided with a real-time relational database, promptly group's sequence list is writing down the relation table that generates at backstage SQLSERVER database in this real-time relational database.This group's sequence list is exactly the user's selecting sequence information that is writing down this group.In each CPU (central processing unit) MP, the record of this group's sequence list all exists.In the record of this group's sequence list, a dynamic field is arranged, writing down the current order of preference of this group.Every choosing once, this field is a dynamic refresh.For described DNH group,, then begin choosing from article one subscribers feeder if dial Indicating Number.If dial each subscribers feeder number, rather than dial Indicating Number, then look in proper order, according to the module of subscribers feeder number searching to this subscribers feeder place from the current number place of dialing, send the process of asynchronous message, find group's sequence list record of this module to the place module.The subscribers feeder of current selection is exactly that the last order of selecting adds 1, and this field of dynamic refresh.If chosen last user, when being line selection, just no longer choosing is gone down, and just starts anew to select when being polling.
Judge that the current subscribers feeder that finds whether in this module, in this way, then finds the respective user line in this module; As not being then to send asynchronous message to subscribers feeder place module; Judge then whether this subscribers feeder is idle, as then selected this subscribers feeder of free time, then do not seek next subscribers feeder as idle, and send a message to the module at its place, until all modules of traversal and find the subscribers feeder of a free time, as can not find idle subscribers feeder, then send busy tone to the calling subscriber.
B, at last after the logic number of selected subscribers feeder, database process is to the Service Logic Number of the database process broadcasting current selected of all called subscribers' module, database process on each module is write table again according to these data, thereby reach the purpose of upgrading the data on this module, i.e. the synchronous real-time relational database record sheet of each module R_PBXSEQ record.Final data storehouse process sends to business process and finds this Service Logic Number message, and business process obtains user's authority according to this message, ring and continuing, and called subscriber's off-hook is finished conversation.
As shown in Figure 3, for the inventive method based on the schematic diagram of an embodiment of business groups system of stored-program control exchange, this is a multi-module system, in commercial affairs group's the subscriber unit (SP) of user distribution on each module.A plurality of subscriber unit SP are connected on the network board of public exchange by 2 8MHW lines and digital switching network respectively, this public exchange and built-in local area network (LAN) are connected data server 110, this data server 110 is used for managing the related data of public exchange, and the agreement of the data that database server is generated by inside is sent among the CPU (central processing unit) MP of each user place module.
As shown in Figure 3, when the number 4560001 that the outer user 3790000 of group dials group is the party A-subscriber, according to the flow chart of as shown in Figure 2 realization DNH group.At first search foreground real-time relational database record sheet R_PBXSEQ, find that the last position of dialing is the logic number 4560003 of subscribers feeder, and on the CPU (central processing unit) MP3 of this subscribers feeder place module, the call proceeding processing of the CPU (central processing unit) MP3 of this module is issued message related to calls in call proceeding immediately.The call proceeding of the CPU (central processing unit) MP3 of this module receives the current state of promptly judging user 4560003 after the message, if its state free time, then directly select this user to get final product, and be that current location adds 1 the dynamic field of the real-time relational database record sheet R_PBXSEQ of global table.If the user of the logic number of this subscribers feeder 4560003 converses, the next user's 4560004 of sequential search module No. then, and send asynchronous message and handle with this to the call proceeding of this subscribers feeder respective modules, simultaneously should pre-processing module to the synchronous global table R_PBXSEQ of each module.
If what dial is the Indicating Number 4560000 of group, then begin in caller place module, search its real-time relational database record sheet R_PBXSEQ record, find the module of first subscribers feeder, and send the call proceeding of message to this module.If receiving, the call proceeding of this module finds first user's free time after this message then ring and continuing, wait for its off-hook, finish processes such as conversation, and to the synchronous current real-time relational database record sheet R_PBXSEQ of all modules, otherwise to traveling through each module until finding next idle user.If still search user after the traversal, then send busy tone to the calling subscriber less than the free time.
Although above-mentioned the preferred embodiments of the present invention that have illustrated and described, one of ordinary skill in the art should be appreciated that can be under the situation that does not exceed the scope of the invention, implement the replacement that is equal to of various changes, distortion or parts, therefore the present invention is not subject to disclosed realization specific embodiments of the invention, the present invention includes all possible embodiment that drops within the claims.
